Description
Built to handle demanding commercial environments, the Eaton QCHGFEP2020 is a 20A, two-pole equipment protection breaker. It provides a 30mA trip threshold specifically calibrated to shield machinery from ground faults, distinct from standard 5mA personnel GFCI devices. The breaker features a cable-in/cable-out unit mount design, making it adaptable for enclosures and control panels without requiring a specific busbar. It delivers a robust 22kAIC interrupting rating and HACR certification.Specifications

Product FAQs
6 answersWhat is the difference between the QCHGFEP2020 equipment protection breaker and a standard GFCI?
The QCHGFEP2020 is a Ground Fault Equipment Protection (GFEP) breaker with a 30mA trip threshold, designed to protect machinery from equipment-damaging ground faults. Standard GFCI breakers use a highly sensitive 5mA trip threshold intended strictly for personnel protection.
How is the QCHGFEP2020 breaker mounted in an electrical system?
This Quicklag breaker features a cable-in/cable-out, feed-thru design for unit-mount applications. It can be installed in standalone enclosures using its box lugs or mounted to a DIN rail, rather than plugging or bolting directly onto a panel busbar.
What wire gauge is supported by the terminals on the QCHGFEP2020?
The line and load side box lugs accept copper or aluminum conductors ranging from 14 AWG to 4 AWG.
Does the QCHGFEP2020 require a neutral connection to operate?
Yes, this breaker is equipped with a pigtail neutral wire. The pigtail must be connected to the neutral bus in your panel or enclosure to power the internal ground fault monitoring circuitry.
What type of trip unit is used in the QCHGFEP2020?
It utilizes a fixed thermal-magnetic trip unit that provides Long-Time, Instantaneous, and Ground-Fault (LIG) protection.
Are Eaton and Cutler-Hammer QCHGFEP2020 breakers the same?
Yes. Eaton acquired Cutler-Hammer, and the QCHGFEP2020 catalog number is identical across both brands. They share the same physical dimensions, mounting style, and electrical ratings.
